To all whom it may so a-cm it known that l, Paras G. MacGnnoon, acitizen of the United States, and resident of the city, county, andState of New York,

have invented certain new and useful improvements 111 Contact-Odors, ofwhich the iollowing 1s a specification.

This invention relates to a device for oil-, mg the contact members oran electric clr-j cuit closing device.

The object of the invention is to provide a device or anattachmentespecially adapted for use with street car controllers forreducing the wear and friction between the contact members.

standard construction.

In the drawings like parts or the several views have been given the samereference numeral.

Figure 1 is a sectional plan view of a por-' tion of a controllershowing the oiling device attacheo thereto. Fig. 2 is a side elevationof a portion of Fig. 1. Fig. 3 is an enlarged sectional view on the hue3-3 of Fig. 1. Fig. i is an enlarged sectional View of the controller,such as 1, 2 and 3, are rotatively mounted upon a shaft 4 and op:

erated in the usual. manner by means of 'a hand cranlr or lever. notshown. The contact lingers 5 and 6 are carried by resilient members,such as 7, upon a suitable support 8 attached to the base of" thecontroller. These parts may be of any standard construction for a deviceof this natureand no novelty is claimed for these features.

The oiling device consists of a number of blocks of absorbentinate1'ial,'such as felt, shown 9 and 9, the block 9 may be partiallyinclosed on two sides by a strip of in sulating material 10 and mountedat one end of a resilient member 11, which is attached at its oppositeend to the contact finger 5. The resilient member 11 is preferablyformed so that when the same is in position,

the surface of the block 9 projects ing a portion of the oil orlubricating material with which it is saturated to the surface thereofand then as the contact is rotated the oil will be distributed over theface of the contact. It will be understood that a number of theseabsorbent blocks are provided and positioned over each series ofcontacts, as shown in Fig. 2.

For supplying oil or lubricating material to the absorbent blocks, aflexible tubular member 12 is provided. This flexible tubular memberextends through the series of absorbent blocks, as shown in Fig. 2, andis provided at its upper-end with a funnel shaped member 13. At thepoints where the flexible tubular member 12 passes through the absorbentblocks, a series of openings, such as shown at 14 vand 15 in Fig. 3, areprovided. These openings decrease in size from the upper to the lowerend so that when the oil is poured into the receptacle 13, filling theflexible tubular member 12, the same will be supplied to and absbrbed bythe blocks in substantially uniform amounts. As the oil is absorbed thelevel of the same in the tubular member 12 falls so that the period oftime during which the same is supplied to the upper block is less thanthat for-the lower blocks. The decreasing size of the openings thusprovides for a uniform supply of oil.

In the modification shown in Figs. 4 and 5 a cover 16 of insulatingmaterial is positioned over the contacts and the absorbent blocks 17project through openings therein so as to engage the contacts of thecontroller in the manner just described. The absorb ent blocks aremounted in a movable holder 18 and are resiliently held in position bymeans of a spring 19 positioned in a retaining member 20 mounted uponthe cover 16. A flexible tubular member 21 supplies the oil to theabsorbent blocks in the manner just described.

In the modification shown in Fig. 6, the construction is similar to thatdescribed and shown in Figs. 4 and 5, except that the cover 16 isomitted and an insulating support 22 substituted, which carries theseries of absorbent blocks.

g isms is It Will thus be seen that each series of contacts is providedwith an independent oiling device and that the flexible tubular memberprovides "convenient means for supplying a uniform amount of oil to theabsorbent members simultaneously and at the same time permitting anindependent rela the movement of the blocks when the contacts oftlie'controller are rotated Whatl claim is;

Lin a device of the class described, the combination with' a series ofmovable. contacts, of a series of absorbent members each positioned toengage one of said contacts, and means for supplying oil simultaneouslyto said absorbent members, said means being adapted to permit anindependent movement of said members.

2. In a device of the class described, the

combination with a series of movable contacts, of a series of absorbentmembers each positioned to engage one of said contacts, and meansconnecting said members and adapted to supply oil simultaneously theretoand to permit an independent movement thereof.

3. In a device of the class described, the combination with a series ofmovable contacts, of a series of absorbent members in sulated from eachother and each positioned to engage one of said contacts, and means forsupplyin oil simultaneously to said absorbent members, said means beingadapted to permit an independent movement of said members.
